Abstract

A work support server is a work support apparatus and acquires biological data on plural workers who engage in shared work for operation of a plant, estimates a state of each of the plural workers on the basis of the biological data on the plural workers, makes an analysis of a state of each of the plural workers, and determines, on the basis of a result of the analysis, whether or not intervention in the shared work by the work support apparatus is necessary.

What is claimed is: 
     
         1 . A work support apparatus, comprising:
 an acquisition unit that acquires biological data on plural workers who engage in shared work related to operation of a plant;   an analysis unit that estimates a state of each of the plural workers on the basis of the biological data on the plural workers and makes an analysis of the state of each of the plural workers; and   a decision unit that determines, on the basis of a result of the analysis by the analysis unit, whether or not intervention in the shared work by the work support apparatus is necessary.   
     
     
         2 . The work support apparatus according to  claim 1 , further comprising:
 an execution unit that executes intervention in the plant where the shared work is carried out, wherein   the decision unit determines an intervention means for the plant in a case where abnormality has been detected by the analysis unit, the abnormality being in a worker engaging in work, and   the execution unit executes intervention for the plant on the basis of the intervention means.   
     
     
         3 . The work support apparatus according to  claim 2 , wherein
 the acquisition unit further acquires operation data collected from a plant device installed in the plant, work environment data related to an environment in the plant, the environment being where each of the plural workers engages in work, and work data related to work that each of the plural workers engages in,   the analysis unit estimates a physical or psychological state as the state of each of the plural workers on the basis of the biological data collected from a device worn by each of the plural workers, and detects the abnormality in a case where a ratio of workers indicating a predetermined state to the plural workers engaging in the shared work exceeds a threshold,   the decision unit determines the intervention means by using the state of each of the plural workers, the operation data, the work environment data, and the work data, and referring to correspondence relation data indicating a history of invention in the plant, and   the execution unit makes a notification to a predetermined worker or a person concerned with the predetermined worker or executes control of the plant device, according to the intervention means determined.   
     
     
         4 . The work support apparatus according to  claim 3 , further comprising:
 a classification unit that determines a work process of each of the plural workers by using the work environment data and the work data and makes a classification of the plural workers by the work process shared, wherein   the analysis unit analyzes, on the basis of a result of the classification by the classification unit, a state of each of the plural workers who engage in the shared work.   
     
     
         5 . The work support apparatus according to  claim 3 , further comprising:
 a training unit that trains a machine learning model that outputs an evaluation index for the plant in response to input of time-series data including the biological data, the operation data, the work environment data, or the work data; and   a prediction unit that predicts, on the basis of a result obtained by input of the biological data, operation data, work environment data, or work data changed by execution of the intervention into the machine learning model that has been trained, time evolution of the evaluation index from a time point of the execution of the intervention.   
     
     
         6 . The work support apparatus according to  claim 5 , wherein the decision unit determines the intervention means by using the time evolution predicted by the prediction unit, from plural intervention means selected by reference to the correspondence relation data. 
     
     
         7 . The work support apparatus according to  claim 5 , wherein the decision unit determines the intervention means from a history of intervention based on the time evolution of the evaluation index predicted by the prediction unit, from plural histories of intervention included in the correspondence relation data. 
     
     
         8 . The work support apparatus according to  claim 3 , wherein the decision unit determines the intervention means that has been specified, from plural intervention means selected by reference to the correspondence relation data. 
     
     
         9 . A work support method executed by a work support apparatus, the work support method comprising:
 an acquisition process of acquiring biological data on plural workers who engage in shared work related to operation of a plant;   an analysis process of estimating a state of each of the plural workers on the basis of the biological data on the plural workers and making an analysis of the state of each of the plural workers; and   a determination process of determining, on the basis of a result of the analysis made through the analysis process, whether or not intervention in the shared work by the work support apparatus is necessary.   
     
     
         10 . A computer-readable recording medium having stored therein a work support program that causes a work support apparatus to execute a process comprising:
 an acquisition step of acquiring biological data on plural workers who engage in shared work related to operation of a plant;   an analysis step of estimating a state of each of the plural workers on the basis of the biological data on the plural workers and making an analysis of the state of each of the plural workers; and   a determination step of determining, on the basis of a result of the analysis made through the analysis step, whether or not intervention in the shared work by the work support apparatus is necessary.
